Top priorities for website improvement
- Add width and height attributes to all image tags. The width and height you specify should be the same as the source image. If you want to resize an image in the browser, use CSS. (read more)
- Avoid use of file extensions wherever possible. File extensions appear at the end of web addresses, and have several negative effects. They make the address harder to remember or type (particularly for non-technical users), and can reveal the underlying technology of the website making it very slightly more vulnerable to hackers. They also tie the implementation of the website to a specific technology, which can make subsequent migration of URLs difficult. Consider URL rewriting as an effective and transparent means of creating appropriate URLs. (read more)
- Consider shortening long anchor text. (read more)
URL format4.0

- All URLs include a file extension.

Images4.4
23% of images have a clearly defined size
No images are being resized by the browser
- Most images (77.0%) don't have defined sizes using width and height attributes in the HTML. These attributes are optional, but strongly recommended as they help the browser arrange the page more quickly.
- Add width and height attributes to all image tags. The width and height you specify should be the same as the source image. If you want to resize an image in the browser, use CSS.
Non Explicitly Sized Images
- Add width and height attributes to all image tags. The width and height you specify should be the same as the source image. If you want to resize an image in the browser, use CSS.
- 7 images are not in a web-friendly format.
- Make sure all images on this website are JPEG, PNG, SVG or GIF format.
Non Web-Format Images
- Make sure all images on this website are JPEG, PNG, SVG or GIF format.
Amount of content8.9
Rendering Chart...
- This website has an average of 606 words per page. The amount of content on a website has been shown to correlate with its search engine ranking.
Amount of content discovered
Headings9.0
- All pages were found to use defined headings. This is excellent as it allows visitors and search engines to summarise the content of webpages quickly. Correctly defined headings aid accessibility and are particularly important for search engine optimisation.
- Some pages did not define headings correctly. The H1 tag should be used for the most top-level heading, with H2 being used for sub-headings and H3 for further sub-headings and so-on. Not conforming to this convention may confuse visitors.
- Ensure that headings are defined in a semantically correct way, i.e. always start with a H1 tag. This is used to summarise the page content. Further tags (H2, H3, H4 etc) are meant to summarise and partition sections within the content.
Page headings detail
Internal links9.1
- One link uses text that is too long. Links should describe what they link to briefly. Linking a long block of text usually indicates an attempt to trick search engines into ranking those keywords highly (a strategy which does not work). Long linked blocks of text are also harder for people to scan.
- Consider shortening long anchor text.
Overly long link text
Link URL Link text Page URL diagnostics.roche.com/.../sexual-health.html Sexual Health Sexually transmitted infections are on the rise. Having access to screening and diagnostic testing is often the first line of defense. The impact of diagnostics and innovative testing can transform STIs into manageable conditions. diagnostics.roche.com/.../product-category.html
- Consider shortening long anchor text.
- 9 links have no text describing their destination. Links on a page should describe their destination for the benefit of both screen readers and search engine spiders.
- Add meaningful anchor text that describes the link's destination. If the link contains an image, ensure you have provided alt text.
Empty link text
- Add meaningful anchor text that describes the link's destination. If the link contains an image, ensure you have provided alt text.
Server behaviour9.4

Compression

- This website uses a temporary (HTTP 302) redirect from http://www.diagnostics.roche.com to http://diagnostics.roche.com. This is OK, but a permanent (HTTP 301) redirect is considered best practice.
